[0003] 2. Description of Related Art
[0004] U.S. Patent Application Publication No. 2011/0167869,
published on Jul. 14, 2011 discloses a modular jack used for 10
Gbps Ethernet. The modular jack comprises an insulative housing
defining a lower inserting port, an upper inserting port stacked
thereon, and a mounting port located behind the lower and upper
inserting ports. An inserting module is assembled from the mounting
port to the inserting ports. The inserting module comprises a set
of upper mating contacts each having a contacting portion extending
into the upper inserting port, a set of lower mating contacts each
having a contacting portion extending into the lower inserting
port, a first magnetic module received in the mounting port and
electrically connecting with the upper mating contacts, a second
magnetic module received in the mounting port and electrically
connecting with the lower mating contacts, and a conductive
shielding member disposed between the first and second magnetic
modules for shielding electromagnetic interference (EMI)
therebetween. The conductive shielding member is made of a metal
plate and is sandwiched between two foam inserts. The conductive
shielding member has three top taps for inserting and soldering to
a top printed circuit board (PCB) and six bottom taps for inserting
and soldering to a lower PCB. The metal plate is stamped from metal
material which is expensive and the cost of the stamping dies is
also high. Moreover, mounting the taps to corresponding holes of
the PCBs and soldering the taps to PCBs are also complex and
time-consuming.
[0005] An electrical connector with low manufacturing cost is
desired.
SUMMARY OF THE INVENTION
[0006] Accordingly, an object of the present invention is to
provide an electrical connector with a simple structure and low
manufacturing cost.
[0007] In order to achieve the object set forth, the invention
provides an electrical connector comprises an insulative housing
defining a lower inserting port, an upper inserting port stacked
thereon, and a mounting port located behind the lower and upper
inserting ports. The inserting module is assembled from the
mounting port to the inserting ports. The inserting module
comprises a set of upper mating contacts each having a contacting
portion extending upwardly and backwardly into the upper inserting
port, a set of lower mating contacts each having a contacting
portion extending downwardly and backwardly into the lower
inserting port, a first magnetic module received in the mounting
port and electrically connecting with the upper mating contacts, a
second magnetic module received in the mounting port and
electrically connecting with the lower mating contacts, and a
conductive shielding member disposed between the first and second
magnetic modules for shielding electromagnetic interference (EMI)
therebetween. The conductive shielding member is a flexible member
and connecting with the PCBs through pressing. The flexible
shielding member does not need taps for being assembled into holes
of the PCBs and soldered thereto. The manufacturing and assembling
cost of the flexible shielding member is lower than a metal
plate's.
